What objects are Both biotic and abiotic?

Answer 1

No objects exist that are both biotic and abiotic. An object is considered "biotic" if it is living or was living at one time (is now dead). Examples include decaying logs, animals, leaves on the forest floor, seeds, etc... An object is considered "abiotic" if it is non-living -- it is not alive now, nor was it ever alive. Examples include waterfalls, clouds, the sun, rocks, etc...

Answer 2

An example of an object that is both biotic and abiotic would be a tree. The living parts of the tree, such as the leaves and roots, are biotic components, while the non-living parts, such as the soil and sunlight, are abiotic components.
